Well guess what...my car works again! You won't believe what the problem was. The very first time the car went out on me was because the battery went dead. My dad jump started the car and I brought it home. Then my husband and I bought a new battery and he installed it. That's when the car wouldn't start again so we began searching for the problem. My dad, thinking that the battery was connected right never thought twice about looking at it. He happened to see a little red sticking out of the wire on the negative side and said this belongs on the positive. So he switched the wires and that was it! The car works fine now. I'm happy we finally figured it out. It was so simple but I guess sometimes you overlook the smallest things. Well, thanks to everyone who tried to help :-)
